About NDA Attempt Calculator
What This Website Does
NDAAttemptCalculator.com helps students figure out how many NDA exam attempts they have left. The UPSC conducts the NDA & NA examination twice a year, and eligibility is based entirely on age — specifically, whether a candidate will be between 16.5 and 19.5 years old on the course commencement date.
Because UPSC does not cap the number of attempts, the total number of chances a student gets depends on their date of birth. This calculator takes a candidate's DOB and maps it against every upcoming NDA exam to show exactly which ones they can apply for.
Why This Website Exists
The NDA eligibility rules around age and course commencement dates confuse many students. The age is not counted from the exam date — it is counted from the date the training course starts at the National Defence Academy (January for NDA I, July for NDA II). This tool exists to give students a clear, instant answer instead of making them calculate it manually from the UPSC notification.
How We Get Our Information
All eligibility rules, DOB ranges, and exam dates on this website are based on the official UPSC NDA & NA notification published at upsc.gov.in. The age formula (16.5 to 19.5 years on the course commencement date) has been consistent across NDA notifications.
For future exam cycles where the official notification has not yet been released, the calculator uses the same standard formula to project DOB ranges. These projections are clearly marked. Once the official notification is published, we update the data to match.
